Application flled February 2, 1920. Serial No. 356,637.

To all whom it may concern:

Be it known that I, Oris W. citizen of the United States, residing at Allerton, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Devices' for Holding and Displaying Maps, Diagrams, &;\.; and I do hereby declare the following to. be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a device for holding and displaying maps, diagrams, etc., and aims to provide an extremely siml ple and convenient means for holding a Inap, diagram or the like, within small compass and enabling same to be displayed conveniently.

A further object is the provision of such a device embodying a web containing the map, diagram, or the like, wound upon two rolls, and the arrangement being such that the map or diagram can be unwound from one roll and wound upon the other to bring the successive portions of the map into view, and without requiring a special -mounting for the rolls or other complicated structure as usually employed for this purpose.

It is also the object of the invention to provide a device of the nature indicated which will serve as a protection for the map or diagram, and enabling it to be carried within small space, as well as alfording convenient means for bringing the successivev portions of the map into view.

VVith the foregoing and other objects in view, which Will `loe apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spiritl of the invention.

The invention is illustrated in the accompanying drawing, wherein:--

Figure 1 is a perspective view of the device, portions'being broken away.

Fig. 2 is a side elevation thereof showing how the hand can be used for unwinding the web from one roll, and Winding it on the other.

In carrying out the invention, two rolls 1 of suitable size are employed, and they can be of any suitable material. A pliant Web 2 of suitable length and width is wound MoonE, aA

Iin opposite directions on the rolls, and consists of a sheet 3 of fabric or other' suitable non-tearing flexible material on which the map, diagram, or the like is disposed, as at 4. A sheet 5 of celluloid or other transparent material is disposed over the map or diagram and is coextensivein width and length with the sheet 3, so as to protect the map or diagram from being soiled in handling or otherwise marred. The ends of the web can be secured to the rolls 1 in any suitable manner, if desired.

The web 2 is wound upon the rolls until the two wound portions of the web contact with one another, and one or more elastic bands 6 of rubber or other elastic material embrace the rolls and thus hold them in frictional contact as well as keeping the web wound on the rolls. These bands will hold the device within small Compass, and in holding the wound portions of the web in contact, will prevent the web from unwinding from either roll, thereby holding the exposed portion of the map in place. The device can thus be conveniently carried or stored away, and the transparent covering or sheet 5 will protect the map or diagram from being soiled or injured. By placing the rolls on a surface and placing the palm of a hand on the web, and moving the hand in either direction, the web can be unwound from one roll and wound on the other, the wound portions of the web slipping past one another, and the celluloid sheet 5 facilitating such slippage Where the wound portions contact. In this Way, the successive portions of the map or diagram, Which can be of any suitable length, are brought into view. Thus, an observer in an automobile, airplane, train or other vehicle, can turn,7 or advance the map or diagram as the vehicle progresses enabling the observer to make comparisons or observations.

The device is not only usefulfor holding maps or diagrams of routes traveled, but can also be used for holding drawings, diagrams, blue prints and the like. A further advantage of the device resides in the fact that a number of'them can be used for holding sections of a large map or diagram, and the devices can be placed with the webs edge to edge and the rolls end to end, thereby setting up the 'map without requiring rolls of considerable length. The several sets of rolls can thus be carried and stored within smaller space, and, furthermore,

each section ofthe map can be used'lseparately. .Acardinal feature of the inven'tion is the absence of a casing or other mounting for the rolls, and the convenience with which the ma or diagram. can be carried and storedan' the successive portions thereof brought into view without denger of the web unwinding accidentally.`- I

The' rolls may *also be conveniently grasped Iightly by both hands, and by a sli ht rotating' and reciprocal pressure, the is easily rolled from one` roll .to the:

other. V

Having thus described the invention, what is claimed as new is 1. A device for holding and displa ing vmaps, diagrams, etc.,'comprising' a web aving woun portions, and'. means embracing said wound' portions Vfor holding them .wound and vin another. 2. VA device for holding and displa. ing

.frictional lcontact with one maps, diagrams, etc., vcomprising rol s,I a`

web wound upon said rolls, and means embra'cing said webs androlls for holding the' web wound on the rolls and said wound portions in frictional contact. a

'3. A device. for holding and -displa ing maps, diagrams, etc., comprising a web av- `and an elastic. band embraci I holding said portions woun and in fric- 'for .holding ing portions wound in opposite directions, said web for tional contact with one another.

3 4. lA device for holding and displa ma s,` diagrams, etc., comprising a pair o rol s, a web wound in opposite directions L I lponsaid rolls, and an elastic band embracmg said web and rolls for holdin the wound' portions of the web on the roll and said wound portions in frietional contact.

5. ,A device for homingt'nd displaying.

ma s, diagrams, etc., comprising a pair o rol s, a web having a sheet for the map,

diagram' orthe like, and a transparent covering, said web being wound in op osite directlyons on the rolls, and an elastic and embracing said web and rolls for holding the Iweb wound on the rolls and for holding said
